WIRE-STRETCI-IER.

Specification of Letters Patent.

Patented Dec. 28, 1915.

Application filed November 10, 1914. Serial No. 871,342.

To all whom it may concern:

Be it known that I, MARION JARvrs, a citizen of the United States, residing at Lathrop, in the county of Athens and State of Ohio, have invented certain new and useful Improvements in VVire-Stretchers, of which the following is a specification.

This invention relates to improvements in wire stretchers, more particularly to devices of this character employed for stretching the strand wires of fences, but which may be employed for other purposes if preferred, and has for one of its objects to simplify and improve the construction and increase the efliciency and utility of devices of this character.

Another object of the invention is to provide a simply constructed device which may be applied to supporting structures such as a fence post without changing the post, and which may be adapted to posts and like supporting structures of various sizes and forms and without structural change in the device.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a side elevation of the improved device applied. Fig. 2 is a transverse section on the line 22 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

The improved device comprises a base or supporting member 10 having hooked projections 11-12 at its terminals and with a pivot pin 13 intermediate the hooks. An operating lever represented as a whole at 14 is mounted to swing upon the pivot 13, the aperture for the pivot being located a short distance from one end of the lever. The lever 1d thus operates in the path of the hooked projections 11-12 and is limited in its movement thereby. At its shorter ter minal the lever is formed with a terminal hook 15, while a laterally directed hook 16 is directed from one side of the lever l t and spaced from its pivotal point at the opposite side a distance substantially equal to the distance from the pivot to the hook 15. The hook 16 is of the open form with its bill or point directed away from the pivot, while the bill of the hook 15 is directed toward the opposite side of the lever from the hook 16, the object to be herein after explained.

The hooked projections 1112 are utilized to receive the links of a chain 17 which is deslgned to pass around a supporting structure such as the post 18, and thus support the member 10 upon the post. By this means the member 10 is firmly supported at any desired point upon the post and ad usted thereon to any required extent, and also supports the lever 14: for vibratory movement upon the pivot 13 relative to the post and to the member 10 and between the hooked projections.

A pull member such as a section of a chain indicated as a whole at 19 is employed and proyided at one end with a wire gripping demos of suitable construction and indicated conventionally at 20. At its opposite end tiie member 19 is provided with a ring 21 to which chains 2223 are coupled. One of the links of the chain 22 is designed to be coupled with the hook 16, while one of the links of chain 23 is designed to be coupled with the hook 15 as shown in Fig. 1. The lever 14 in Fig. 1 is shown disposed obliquely to the longitudinal axis of the post or in the position which it will occupy just after strain has been applied to the chain 22. This movement will apply strain to the chain 23, and when the lever has been moved as far toward the left as the hooked projections will permit the link of the chain 28 nearest to the hook 15 will be engaged with this hook and thus place the device in position to apply strain to the member 19 when the lever is moved in the opposite direction, and then the operation repeated relative to the chain 22 and so on continuously, as will be obvious.

The base member 10 having the terminal projections 1112 and adapted to be adjustably supported upon the post 18 with the lever 1 1 pivoted thereon and operating between the projections and limited in its movement thereby is an important feature of applicants device, and materially increases its etliciency and utility. This construction enables the device to be adjusted vertically upon the post to adapt it to the strand Wires of a fence one at a time, or to a fence Webbing by employing any of the Well known clamping devices.

The improved device is simple in construction, is constructed Wholly of metal, is strong and durable, and may be constructed of any required size to adapt it to the size of fence with which it is employed.

Having thus described the invention, What is claimed as new is:

1. A device of the class described comprising a base member, a lever pivoted intermediate its ends centrally of the base, means carried by the lever at opposite sides of its pivot for attaching pull members, and projections at the terminals of the base adapted to receive holding means and extending into the path of the lever and limiting its movements and preventing it from assuming abnormal positions,

2. A device of the class described comprising a base member, a lever pivoted intermediate its ends centrally of the base, hook devices carried by the lever at opposite sides of its pivot and opening in opposite directions, said hook devices adapted to receive pull members, and projections at the terminals of the base adapted to receive holding means and extending into the path of the lever and limiting its movements and preventing it from assuming abnormal positions.

In testimony whereof I afiix my signature in presence of tWo Witnesses.

MARION JARVIS.
